FrHun eefe6e35ac LibGUI: Add option to move Toolbar items to overflow menu in groups
When items are sent to the overflow menu one by one, it can happen that
buttons that are heavily related, and don't make sense without one
another (either visually or logically) are separated.
This new option enables the developer to choose the "grouping"
behavior, of sending all items that are not separated to the overflow
menu together, as soon as one of them doesn't have enough space to be
displayed. (provided the toolbar is set as collapsible)
